This paper presents a component framework for inter-organizational collaboration in value networks in the domain of strategic supply network development. The domain chosen extends the traditional frame of reference in strategic sourcing from a supplier-centric to a supply-network-scope. The basic functionality provided by the component framework and discussed in this paper is the dynamic modeling of strategic supply networks and the collaboration between requestors and suppliers in a dynamic network. The corresponding component model is introduced and the functionality provided by the modeling component discussed in detail. The problems of heterogeneity that come up in inter-organizational communication and collaboration will be addressed by introducing a collaboration component that guarantees correct interchange and representation of application data. It is shown what kind of interoperability problems will be encountered in the strategic supply network development scenario as well as how the communication and collaboration component is able to cope with these problems.
